A salient tactic used in online communication about anthropogenic climate change is to accuse the opposite side of being untruthful. This hoax discourse identifies one side as deniers of scientific facts and the other side as manufacturing false alarm. We study the hoax discourse on climate change in the English-speaking blogosphere as a disruptive discursive practice. The study uses automated, qualitative, and quantitative content analysis as well as network analysis to identify the main patterns of the hoax discourse, drawing on a sample of almost 50,000 blog posts related to climate change published online for one year, from May 14, 2016, to May 14, 2017. The study shows that hoax discourses are a salient feature of online debates. They engage both mainstream voices and contrarians in mutual accusations. Accusations of untruthfulness are rarely voiced in a way that identifies concrete lies and liars; instead, they form part of broad attacks designed to vilify the other group. The discourse does not directly address the other side of the debate. It does not constitute a deliberation, but rather serves to affirm one’s social group identity and exacerbate mutual group polarization.Downloads

Fair Use
The U.S. Copyright Act of 1976 specifies, in Section 107, the terms of the Fair Use exception: Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include:- the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
- the nature of the copyrighted work;
- the amount and substantiality of the portion used in relation to the copyrighted work as a whole; &
- the effect of the use upon the potential market for or value of the copyrighted work.
The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors. In accord with these provisions, the International Journal of Communication believes in the vigorous assertion and defense of Fair Use by scholars engaged in academic research, teaching and non-commercial publishing. Thus, we view the inclusion of “quotations” from existing print, visual, audio and audio-visual texts to be appropriate examples of Fair Use, as are reproductions of visual images for the purpose of scholarly analysis. We encourage authors to obtain appropriate permissions to use materials originally produced by others, but do not require such permissions as long as the usage of such materials falls within the boundaries of Fair Use.
The International Journal of Communication encourages authors to employ fair use in their scholarly publishing wherever appropriate. Fair use is the right to use unlicensed copyrighted material (whether it is text, images, audio-visual, or other) in your own work, in some circumstances. We consult the Code of Best Practices in Fair Use for Scholarly Research in Communication, created by the International Communication Association and endorsed by the National Communication Association, and you should too. If you have any questions about whether fair use applies to your uses of copyrighted material (whether it is text, images, audio-visual, or other) in your scholarship, simply include your rationale, grounded in the Best Practices, as a supplementary document with your submission.
